Question

I’m working on an app that uses Jena for storage (with the TDB backend). I’m looking for something like the equivalent of Squirrel, that lets me see what’s being stored, run queries etc. This seems like an obvious thing to need, but my (perhaps badly phrased) google queries aren’t turning up anything promising.

Any suggestions, please? I’m on XP. Even a command line tool would be helpful.

Take a look at my Store Manager tool which is part of the dotNetRDF Toolkit which I develop as part of the wider dotNetRDF project I maintain.

It provides a fairly basic GUI through which you can connect to various Triple Stores including TDB provided that you expose your dataset via Joseki/Fuseki. You need to have .Net 3.5 installed to run the apps in the toolkit.

If you don’t already expose your TDB dataset via HTTP try using Fuseki as it is ridiculously easy to use and can be run just on your local machine when necessary to make your TDB store available via HTTP for use with my tool e.g.

java -jar fuseki-0.1.0-server.jar --update --loc data /dataset

Please see the Fuseki wiki for more information on running Fuseki and the various options. In the above example Fuseki is run with SPARQL Update enabled (the –update flag), using the TDB dataset located in the directory data (the –loc data argument) and with a base URI of /dataset for the data.

Once running you can use my tool to connect to a Fuseki server by going to File > New Generic Store Manager, selecting the “Fuseki” tab from the dialog that appears, entering the URI http://localhost:3030/dataset/data and then clicking “Connect to Fuseki”.
